Refresh Roundup: week of August 27th, 2012

Your smartphone and / or tablet is just begging for an update. From time to time, these mobile devices are blessed with maintenance refreshes, bug fixes, custom ROMs and anything in between, and so many of them are floating around that it's easy for a sizable chunk to get lost in the mix. To make sure they don't escape without notice, we've gathered every possible update, hack, and other miscellaneous tomfoolery we could find during the last week and crammed them into one convenient roundup. If you find something available for your device, please give us a shout at tips at engadget dawt com and let us know. Enjoy!

Samsung Galaxy S II HD LTE: Bell's smartphone -- essentially the Canadian version of the ill-fated Skyrocket HD -- is now eligible for an update to Ice Cream Sandwich (Android 4.0.4). [MobileSyrup]

Unofficial Android updates, custom ROMs and misc. hackery

Motorola Xoom WiFi: The Xoom may have already received its update to Jelly Bean, but Motorola's not done with this tablet just yet. The manufacturer is already inviting members of the Motorola Owners' Forum to help test a new software release. [Android Central]

Samsung Galaxy Tab, Galaxy Note (AT&T) and T-Mobile myTouch Q: Nightly builds of CyanogenMod 10 are now available for Samsung's original Android tablet, AT&T's super-sized smartphone and the budget-oriented QWERTY slider from T-Mobile. Though still in relatively early stages, CyanogenMod 10 provides an excellent means to upgrade to Android 4.1. [Android Police 1, 2]

HTC Thunderbolt: Many Thunderbolt owners are likely already aware that HTC missed its promised timeframe of July / August for the delivery of Ice Cream Sandwich. The manufacturer has since acknowledged the slip, and insists that it's currently actively engaged with Verizon to make the update available for Thunderbolt owners. [Android Community]
